  • Watershed Summaries
    Appendix A: Watershed Summaries Preface California’s watersheds supply water for drinking, recreation, industry, and farming and at the same time provide critical habitat for a wide variety of animal species. Conceptually, a watershed is any sloping surface that sheds water, such as a creek, lake, slough or estuary. In southern California, rapid population growth in watersheds has led to increased conflict between human users of natural resources, dramatic loss of native diversity, and a general decline in the health of ecosystems. California ranks second in the country in the number of listed endangered and threatened aquatic species. This Appendix is a “working” database that can be supplemented in the future. It provides a brief overview of information on the major hydrological units of the South Coast, and draws from the following primary sources: • The California Rivers Assessment (CARA) database (http://www.ice.ucdavis.edu/newcara) provides information on large-scale watershed and river basin statistics; • Information on the creeks and watersheds for the ESU of the endangered southern steelhead trout from the National Marine Fisheries Service (http://swr.ucsd.edu/hcd/SoCalDistrib.htm); • Watershed Plans from the Regional Water Quality Control Boards (RWQCB) that provide summaries of existing hydrological units for each subregion of the south coast (http://www.swrcb.ca.gov/rwqcbs/index.html); • General information on the ecology of the rivers and watersheds of the south coast described in California’s Rivers and Streams: Working

  • Southern Steelhead Populations Are in Danger of Extinction Within the Next 25-50 Years, Due to Anthropogenic and Environmental Impacts That Threaten Recovery
    SOUTHERN CALIFORNIA STEELHEAD Oncorhynchus mykiss irideus Critical Concern. Status Score = 1.9 out of 5.0. Southern steelhead populations are in danger of extinction within the next 25-50 years, due to anthropogenic and environmental impacts that threaten recovery. Since its listing as an Endangered Species in 1997, southern steelhead abundance remains precariously low. Description: Southern steelhead are similar to other steelhead and are distinguished primarily by genetic and physiological differences that reflect their evolutionary history. They also exhibit morphometric differences that distinguish them from other coastal steelhead in California such as longer, more streamlined bodies that facilitate passage more easily in Southern California’s characteristic low flow, flashy streams (Bajjaliya et al. 2014). Taxonomic Relationships: Rainbow trout (Oncorhynchus mykiss) historically populated all coastal streams of Southern California with permanent flows, as either resident or anadromous trout, or both. Due to natural events such as fire and debris flows, and more recently due to anthropogenic forces such as urbanization and dam construction, many rainbow trout populations are isolated in remote headwaters of their native basins and exhibit a resident life history. In streams with access to the ocean, anadromous forms are present, which have a complex relationship with the resident forms (see Life History section). Southern California steelhead, or southern steelhead, is our informal name for the anadromous form of the formally designated Southern California Coast Steelhead Distinct Population Segment (DPS). Southern steelhead occurring below man-made or natural barriers were distinguished from resident trout in the Endangered Species Act (ESA) listing, and are under different jurisdictions for purposes of fisheries management although the two forms typically constitute one interbreeding population.

  • 4 Tribal Nations of San Diego County This Chapter Presents an Overall Summary of the Tribal Nations of San Diego County and the Water Resources on Their Reservations
    4 Tribal Nations of San Diego County This chapter presents an overall summary of the Tribal Nations of San Diego County and the water resources on their reservations. A brief description of each Tribe, along with a summary of available information on each Tribe’s water resources, is provided. The water management issues provided by the Tribe’s representatives at the San Diego IRWM outreach meetings are also presented. 4.1 Reservations San Diego County features the largest number of Tribes and Reservations of any county in the United States. There are 18 federally-recognized Tribal Nation Reservations and 17 Tribal Governments, because the Barona and Viejas Bands share joint-trust and administrative responsibility for the Capitan Grande Reservation. All of the Tribes within the San Diego IRWM Region are also recognized as California Native American Tribes. These Reservation lands, which are governed by Tribal Nations, total approximately 127,000 acres or 198 square miles. The locations of the Tribal Reservations are presented in Figure 4-1 and summarized in Table 4-1. Two additional Tribal Governments do not have federally recognized lands: 1) the San Luis Rey Band of Luiseño Indians (though the Band remains active in the San Diego region) and 2) the Mount Laguna Band of Luiseño Indians. Note that there may appear to be inconsistencies related to population sizes of tribes in Table 4-1. This is because not all Tribes may choose to participate in population surveys, or may identify with multiple heritages. 4.2 Cultural Groups Native Americans within the San Diego IRWM Region generally comprise four distinct cultural groups (Kumeyaay/Diegueno, Luiseño, Cahuilla, and Cupeño), which are from two distinct language families (Uto-Aztecan and Yuman-Cochimi).

  • San Dieguito Double Track and Special Events Platform Project Frequently Asked Questions San Dieguito Double Track and Special Events Platform Project
    San Dieguito Double Track and Special Events Platform Project Frequently Asked Questions San Dieguito Double Track and Special Events Platform Project Updated December 13, 2013 Frequently Asked Questions ■ OVERVIEW OF PROJECT 1. What is the purpose of the project? The project will improve a critical part of the 351-mile Los Angeles-San Diego-San Luis Obispo (LOSSAN) rail corridor that serves as a vital link for passenger and freight movements in the San Diego region. The San Dieguito Double Track and Special Events Platform Project will increase capacity and improve system reliability by adding a one-mile segment of double track between Solana Beach and Del Mar, resulting in a continuous 2.8-mile-long segment of double track. The project also includes the replacement of the existing 97-year-old San Dieguito River wooden trestle rail bridge and the construction of a new special events platform that would directly serve the Del Mar Fairgrounds. Additional improvements include construction of new turnouts, signals, retained embankments, and drainage facilities. 2. What is the scope of the project? The project’s engineering and environmental analysis process is underway. The environmental compliance is subject to the requirements of the National Environmental Policy Act (NEPA) process and the Federal Railroad Administration (FRA) is the Lead Agency under NEPA. This project is funded through environmental and design, although not funded for construction. San Diego Association of Governments (SANDAG) works to make all projects shovel ready. Although the start date for construction has yet to be determined, the project is planned to be constructed prior to 2030 according to the SANDAG 2050 Regional Transportation Plan (RTP).

Where did they obsidian from Inyo County over 300 miles away, live? How were they able to survive? At our showing that these people had an extensive meeting on Monday, December 11 at 6 pm in trade network.2 the Chula Vista Library, Dennis Gallegos will answer these questions. His new book, First The First People may have come to the South People: A Revised Chronology for San Diego Bay long before those found at Remington Hills. County, examines the archaeological evidence Scientists from the San Diego Natural History going back to the end of the Ice Age 10,000 Museum have examined mastodon bones years ago. The ancestors of todayʼs Kumeyaay may have come down the coast from the shrinking Bering land bridge. Ancestors who spoke the ancient Hokan language may have come from the east, overland from the receding waters of the Great Basin. These early people (Californiaʼs first migrants) were called the “Scraper-Makers” by the pioneering archaeologist Malcolm Rogers in the 1920s.1 The name came from the stone tools that Rogers discovered at many sites in San Diego County, from the San Dieguito River in the north to the Otay River in the south. Rogers described their culture as the “San Dieguito pattern” based on his research at the Harris site near Lake Hodges on the San Dieguito River. This same cultural pattern and stone tools have been found at the Remington Hills site in western Otay Mesa.
